rLANT^ WRIGIITIAN^.' 



VI. 



Ligules 8 or 10, broaclly obovate, 3-lobed at tbe apex, bright yellow, as are the nii- 

 merous disk-flowers. Pappus of the ray and exterior disk-flowers entirely muticous 

 and obtuse, about half the len^th of the achenium ; of the inner disk-flowers, in- 



cluding their rathcr short scabrous-denticulatc awn, almost as long as the achenium. 

 Thc pappus of some of the intcrmediate flowers is intermediate in character. 

 This plant so much rescmblcs Bahia pedata, No. 387 of Wright's former collection, 

 that I was about to pass it as a variety of that species, with more dissected leaves, 

 when I observcd the elongated and awned palcte of the pappus of all the inner 

 flowers. This is an anomaly in the genus : none of the species except E. pedata 

 show evcn a manifcst midnervc to the pappus.

 Leon ; June. (The original spccimens, No. 387, were gathered on the Limpio.) 



Thc few specimens collcctcd the present season are stouter than those of 1840 ; the 



leaves with larger, broader, and more incised or lobed segments. It still more re- 



scmblcs the following plant ; from which the obtuse and fewer scales of the in- 

 volucre, as well as the pappus, distinguish it. 



ViLLANOVA ciiRYSA^iTiiEMOiDES : puberula, glabella ; caule erecto supcrne panicu- 

 lato ; ramls floridis pedunculisque subcorymbosis viscoso-glandulosis ; foliis alternis 

 1 -- 2-ternatipartitis, segmentis 2 - 3-Iobatis seu pinnatifidis, lobis oblongis vel sub- 



lincaribus obtusis ; involucri squamis subtriseriatis a^qualibus acuminatis ; ligulis 

 16-20 ovali-oblongis ; fl. disci multis. — Amauria'? dissccta, Gray^ Pl. Fendl. p. 

 104. — Sidcs of moimtains, at the copper mines, New Mexico; Oct. (1257.) 

 Stems one to four feet high. Leaves all alternate ; the laro;er ones 2 to 4 inches in 



diamcter, glabrous or iiearly so. Heads half an inch iii diameter, exclusive of the 

 ligules, which are 5 lincs long. Plowers all jcllow. Scales of the involucre 16 to 

 20, herbaceous ; the exterior lanceolate ; the inner oblong-obovate and conspicu- 

 ously acuminate, CoroUas, especially the tube, beset with very glandular short 

 hairs. Branches of the style in the disk-flowers tipped with a short and obtuse 

 cone. Reccptacle rathcr convex. Achenia quadrangular, subclavate, nearly gla- 

 brous, striate, all fcrtile. — This plant is to Bahia proper what the original species 

 of Villanova are to Achyropappus. There is nothing but a larger numbcr of flow- 

 ers in the head to distinguish it froin Villanova, with which it accords very well 

 in habit.
